Spatial-temporal Characteristics of GPS Cycle Slip Frequency

Abstract:

In this paper， the cycle slip detection method of TurboEdit is used to detect the GPS observation data of 357 stations evenly distributed in the continuous operational reference system （CORS） of the United States of America from 2015 to 2019. The spatial and temporal characteristics of the cycle slip detection results are statistically analyzed， and the correlation between the cycle slip frequency（F-CS） and the elevation angle， local time， season and year is discussed. The results show that F-CS values are relatively higher at low altitude angles and there are more cycle slip events between 12：00―18：00 than those in other times. In addition， F-CS values in March and September reach the peak， and F-CS values in March are higher than those in September. It is notable that F-CS values in 2015 are higher than those in other four years.
